Hi Robert

Judging by the screenshot, I'd say its because the coordinate system hasn't been set in the Data Frame properties. And neither are the units set. To keep digitising features that are off-screen, you can use the shortcut key of C while editing to keep panning across...

Hope this helps...

Are you saying that if the shapefile or geodatabase already has a projection, but do I need to set the Data Frame properties needed to be set the coordinate system and units set, too ? If the layer already has a projection and ArcMap should be able to read it and set it automically ?

From my experience if you start the ArcMap with a new map option and then add a shape file, the map frame automatically takes the coordinate system of the shape file. So why should one select it, it should be by default. Well this is while working on 9.2....

While it's true ArcMap will automatically set the coordinate system to match the first data layer with a defined CS added to the map, that screenshot doesn't even show any data in the TOC, just "Layers", which is the default data frame name. But that's beside the point.

Anyway, when I'm digitizing and need to continue past the screen I use the C shortcut key Dustin mentioned to pan the view, rather than let ArcMap pan automatically. It gives you more control over the panning and doesn't interrupt your digitizing.

Everyone: Thanks. Sorry about the graphic i drew. I was in hurry yesterday. I'll keep that in mind about the C shortcut.
